It looks like the last verified contact with them has been in 2018. Recently a youtuber went there and tried to get their attention, but couldn’t find them.
Is it possible they’re not even still around? Maybe a disease found its way onto their island and took them out. It could have even been from the last visitor in 2018.
The Indian government monitors them, and seems to think they’re doing alright.
IIRC the guy from 2018 was an enormous tool that harassed them for a couple months, so maybe they’re just keeping their distance from this tool.
